Prove every user is real — invisibly and continuously.
Invisible, Frictionless Verification
Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
Continuous Behavioral AI
Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
Privacy-Preserving by Design
The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
Effortless Integration
A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
Strengths & Pros
+No CAPTCHAs, popups or friction for genuine users
+Continuous behavioral scoring rather than a one-time human check
+Detects modern AI agents as well as classic bots
+Privacy-preserving: no PII and no cross-site tracking
+
Fast integration via a single script tag with sub-200ms scoring
Limitations
